Biopac PPG100C - Pulse Plethysmogram Amplifier Module

The PPG100C records the pulse pressure wave and provides an indication of blood pressure, blood density or vasoconstriction. The PPG100C couples to a photoelectric pulse transducer (TSD200 or TSD200C*) to measure changes in infrared reflectance resulting from varying blood flow. Front panel controls allow selection of either absolute or relative plethysmographic measurements.

Each PPG100C requires one photoelectric pulse plethysmogram transducer:

  • TSD200 with Velcro for easy attachment to finger OR
  • TSD200C with ear clip

* The older model TSD200B with adhesive collars is no longer sold but works with the PPG100.

Applications Include:

  • Plethysmography
  • Psychophysiology
